If one wishes to 'farm' Ancient bones, it is recommended to build one/two Biologist and one/two Missionary statues, and use their standalone voyages. There is no joint voyage for Ancient bones, unlike other trade goods.

Fletching a scrimshaw requires 10 Ancient bones per scrimshaw created. Fletching a set of 25 lotus darts requires 1 set of ancient bones and 25 ascension shards. The maximum amount of Ancient bones a player can store at one time is 250. Any successful voyages after this will not increase the total.
